The adb command facilitates a variety of device actions, such as installing and debugging apps. adb provides access to a Unix shell that you can use to run a variety of commands on a device. It is a client-server program that includes three components."

Client: A client which sends commands. You can use powershell, cmd…

Server: which manages communication between the client and the daemon. The server runs as a background process on your development machine.

ADB Daemon: which runs commands on a device. We use Andorid Image in VMWare.

Step 2:

You can connect android devices with adb. You need to find the IP address of the virtual android machine:

After that you can use this command:

Step 3:
